2 Claims.

' tapes through the apertured portions thereof and inwardly of onelongitudinal edge of the tape so as to provide a secure attachment ofthe links to the tape; a. further object being to provide a stringertape of the class described fashioned from a single woven fabric bodywherein'one edge portion of the tape is enlarged or beaded and whereinsaid beaded edge joins the remainder of the tape in widely spacedthreads, the thickness of which is less than the width of the links orcoupling elements to be attached to the tape whereby in die casting thelinks on the tape, the inner ends thereof will be united through thetape inwardly ofsaid beaded edge and between the spaced threads orstrands; astill further object being to provide a stringer tape of theclass scoops with the stringer tape; and with these and other-objects inview, the invention consists in a device of the class and for thepurpose specified, which is simple in construction, efficient in use,and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which:

Fig. 1 is a plan view of a part of two stringers of a separable fastenershowing my improved mounting tape or tapes.

Fig. 2 is a transverse sectional view of the structure shown in Fig. 1.

Fig. 3 is a plan view of the stringer tape or mounting member detached.

Fig. 4 is an enlarged sectional view similar to Fig. 2 showing only apart of the construction and showing a. modification; I

Fig. 5 is a view similar to Fig. 4 showing another modification and,

Fig. 6 is a plan view of a part of the construction shown in Fig. 5.

In Figs. 1 and 2 of the drawing, I'have shown at 5 and 5a the tapes ormounting members of a separable fastener stringer including the couplinglinks or scoops 6, 6a attached to'one enlarged or beaded. edge 1, 1a ofthe tapes 5, 5a. The separable fastener is of the type employing aslider movable along the stringers or the links 6, 6a thereof to coupleand uncouple said links in the operation of attaching and detaching thefastener as in other devices of this kind, but the slider and otherassociated parts are 'omitted as they form no direct part of theinvention.

Asthe tapes 5, 5a are of similar construction, the brief description ofone will apply to the other. In Fig. 3 of the drawing, I have shown thetape 5 detached and this tape consists of a single unitary woven fabrichaving a wide attaching end portion 8 inwardly of the beaded edge Ithereof. The beaded edge joins the part 8 in widely spaced strands 9which are, in the construction shown,

part of the cross or weft threads of the fabric. These threads formlongitudinally spaced and relatively large apertures or openings I0 inclose proximity to the beaded edge I. The size of the threads 9 is lessthan the width as well as thick ness of the link 6 to be attachedthereto so as to establish a complete bonding or uniting of each linkthrough at least one of the apertures 10 as indicated at H in Fig. 2 ofthe drawing, and especially when the link 6 and its companion link 6a iscomposed of a casting or die cast body. However, as seen in Fig. 4 ofthe drawing, the link 6b may have a forked inner end l2 which is broughttogether within the openings ill in the strip 5. These forked ends maysimply be brought together by suitable pinching tools, or, if desired,may be cemented together or otherwise secured together as indicated at13 in said figure so as to produce substantially the same result as thatshown in Fig. 2 of the drawing.

While my improvedtape is adapted for use in any type or. kind ofstringer construction or employing links of many types and kinds, itfinds I its principal use in conjunction with the nonmetallic plastic orthermoplastic links, and still more particularly to links composed ofcellulose acetate which may be directly die cast upon the tape orindividually cast and then formed and cemented as seen in Fig. 4 of thedrawing. With these types of links, the tapes 5, 5a may be exposed to orpassed through a solvent solution such for example as acetone, whichbycapillary attraction will quickly extend to the links attached to thebeaded edge of the stringer and operate to cement and secure the linksto the beaded edge as well as to any part of the tape including thethreads or strands S'thereof contacting with said links in a mannertaught more specifically in a companion application filed March 6, 1937,Ser. No. 129,317.

Upon a consideration of Fig. 1 of the drawing, it will appear that thespacing of the threads 9 and the size of the apertures III is such as toprovide a staggered or more or less indefinite location of the links 6,Ba. with respect thereto and this would depend largely upon the size ofthe links employed on the tape as well as the number of strands 8 or thespacing thereof deemed necessary to provide the required strength in theresulting tape. But, due to the fact that the strands 9 will be, at alltimes, less in size than the dimensions of the link, a. bonding of thelink through the apertures formed between the strands will be assuredregardless of the spaced arrangement thereof.

In Figs. and 6 of the drawing, I have shown another modification whereina supplemental mounting tape I4 is employed in conjunction with a tape5, similar to the tape 5 shown in Figs. 1 and 3, the tape l4 consistingof similar side portions 15, l5a joined by an intermediate openwork orapertured section l6 formed by removing a number of the longitudinalthreads in the weave of the strip ll so as to permit the section Hi toslip over the protruding ends of the links 6 and to pass around thebeaded edge I and to be stitched or otherwise secured to the tape 5adjacent the links 6 as indicated at H.

.The supplemental strip l4 may be attached after the stringer tape hasbeen treated with the saturating solution of the solvent employed tosecure the links in position, or this treatment may take place after theattachment of the supplemental strip if desired.

In fastener stringers of the kind under conopen or forked inner end of alink may be brought together in the apertured portion to substantiallycompletely envelop the beaded edge of the tape or these ends may becemented together to produce a more or less unitary coupling body aroundsaid beaded edge. This will make the links as strong as the tape orsubstantially so, depending entirely upon the material employed inconstructing the links.

In the above described operation of cementing the links to the stringertapes either as shown in Figs. 1 and 2 or as shown in Fig. 5, slightpressure may be applied to the links in the cementing or gluingoperation to insure positive engagement of the links with the fibres ofthe tape and to compensate for the softening of the surfaces of the linkadjacent the tape by exposure to the solvent employed. However, thisapplied pressure is only essential where the fastener is to be subjectedto excessive stresses or strains in the article or garment to which itis attached.

Having fully described my invention, what I claim as new and.desire tosecure by Letters Patent, is:

1. In a separable slide fastener, a tape having a head at one edgethereof, a plurality of coupling links mounted on said bead anduniformly spaced thereon, said tape and bead being connected together byspaced substantially parallel strands, each strand being of lessthickness, as measured lengthwise of the tape, than that of one of saidlinks, whereby at least part of each link will pass through a spacebetween adjacent strands, regardless of the position of that linkrelative to a strand, certain of said strands being at least partiallycovered by certain links.

2. In a separable slide fastener, a tape having a bead at one edgethereof, a plurality of coupling links cast on said head and uniformlyspaced thereon, said tape and bead being connected together by spacedsubstantially parallel strands, each strand being of less thickness, asmeasured lengthwise of the tape, than that of one of said links, wherebyat least part of each link will pass through a space between adjacentstrands, regardless of the position of that link relative to a strand,certain of said strands bein at least partially covered by certainlinks.
